Fun Plant: Catnip. Easy to grow. It likes full sun. Good uses for humans: can be dried and drunk as tea and is said to sooth nerves and the digestive tract. The active ingredient in catnip is said to be ten times more effective than DEET at repelling mosquitoes. So grow some around your patio or deck for a natural way to block those pesky mosquitoes.

Fun Plant: Marshmallow. Yep the same one you get the candy from. It's not only good for that but can be used salads (the seeds or the leaves). The sap, seeds, leaves are all edible. It is also used to treat sore throats, coughs, etc. They are fairly hardy plants that are used to cold wet weather. They need to be kept damp.
